Could you explain it in a bit detail? Why is PM domain involved?

Suppose PM domain is involved, its domain runtime_resume callback
is still run in the context with PF_MEMALLOC_NOIO flag set if the
affected 'device' is passed to the callback.

Sorry, could you describe what is the race?

Suppose drivers set correct parent device to the disk device(gendisk),
then add the disk into device model via register_disk(), the solution
should be fine.

Thanks,
